Our flights are Melb-Narita, spend 3 days in Tokyo (we've been once before) then flying over to Fukuoka, and then spend 4 and a bit weeks working our way back to Tokyo via Shinkansen.
Stops in Hiroshima (havent been yet) Kyoto (have been) and Nara (havent been) definitely on the cards, but definitely looking for any and all advice on "west of Osaka" basically.

- The Peace Park is interesting and a bit depressing at the same time,
- I wish I had gone to the Mazda museum but the missus Father (FIL) had been convinced to leave it out of our plans,
- Miyajima island - a short ferry ride - is well worth a visit for around 1/2 a day at least and is amazing at low tide and you can walk around the gate;https://www.japan-guide.com/e/e3401.html
Otherwise at high tide you will see Itsukushima Shrine in all it's glory:https://www.japan-guide.com/e/e3450.html
